■Buzzer operation and dis-
tance to an object
A buzzer sounds when the sensors
are operating.
 The buzzer beeps faster as the
vehicle approaches an object.
When the vehicle comes within
approximately 30 cm (1.0 ft.) of
the object, the buzzer sounds
continuously.
 When 2 or more sensors simulta-
neously detect a static object,
the buzzer sounds for the near-
est object.
 Even when the sensors are oper-
ating, the buzzer will be muted in
some situations. (automatic
buzzer mute function)
■Adjusting the buzzer volume
The buzzer volume can be adjusted
on the multi-information display.

Driving
Object
Calculated vehicle route
When the vehicle is moving, the side sensors or side cameras ca n detect
objects. While the vehicle is moving, if a detected object can no longer be
detected by the side sensors or side cameras, the location of t he object rel-
ative to the vehicle is estimated. If the object is determined to be in the esti-
mated path of the vehicle, the object warning function will ope rate.
Object detected by side sensors or side cameras
1 The vehicle is stopped and objects along the sides of the vehicle are not
detected.
2 Objects are detected as the vehicle is moving.
3 Even though the objects are outside of the detection area of the side
sensors or side cameras, a warning is displayed and a buzzer so unds.
■Object warning function operating conditions
●The Advanced Park is operating.
●The vehicle moves about 7 m (23.0 ft.)
after the EV system is started.
●The R shift position is selected.
●After the D shift position has been selected, the vehicle has moved 7 m
(23.0 ft.) or less.
●Camera switch has been pressed and
the multimedia display is displayed.
●The front or rear sensor detects a sta-
tionary object.
■Detection of objects along the sides of the vehicle
●Objects along the sides of the vehicle are not instantaneously detected. The location of objects in relation to the
vehicle is estimated after they are first detected by the front or rear side sen-sors, or side cameras. Therefore, after

5-4. Using the driving support systems
the power switch is changed to ON,
even if an object is along the side of the vehicle, it may not be detected until the vehicle has been driven a
small amount and the side sensors or side cameras completely scan the areas along the sides of the vehicle.
●If a vehicle, person, animal, etc., is detected by a side sensors or side
cameras, but then leaves the detec- tion area of the side sensors or side cameras, the system will assume the
object has not moved.
WARNING
■Side sensors and side cameras
In situations such as the following, the
function may not operate correctly, possibly leading to an accident. Pro-ceed carefully.
●When starting off shortly after the power switch is turned to ON and a
small vehicle or other object which cannot be detected by a front side sensor is next to the vehicle.
In the situation shown in the following
illustration, even if the vehicle starts
off, the vehicle on the left will not be
detected and the object warning func-
tion will not operate.
●When an object or person is in a position which cannot be detected
by the side sensors or side cam- eras.
●When, after the side sensors have completed scanning the areas along the sides of the vehicle, a
vehicle, person, or other object approaches the side of the vehicle and cannot be detected.
●When the outside rear view mirror is closed, the side sensors or side
cameras cannot detect objects.
●If the 12-volt battery was dis-
charged or has been removed and installed, fold and extend the out-side rear view mirrors.

making their silhouette obscure • Pedestrians whose body is partially hidden by an object, such as a cart or
umbrella • Pedestrians which are obscured by darkness, such as at night
●In some situations, such as the follow-ing, pedestrians may not be detected
by the rear camera detection function, preventing the function from operating properly:
• When backing up in inclement weather (rain, snow, fog, etc.)• When the rear camera is obscured
(dirt, snow, ice, etc., are attached) or scratched• When a very bright light, such as the
sun, or the headlights of another vehi- cle, shines directly into the rear cam-era
• When backing up in a place where the surrounding brightness changes sud-denly, such as at the entrance or exit
of a garage or underground parking lot• When backing up in a dim environ-
ment such as during dusk or in an underground parking lot• When the camera position and direc-
tion are deviated • When a towing hook is attached• When water droplets are flowing on
the camera lens • When the vehicle height is extremely changed (nose up, nose down)
• When tire chains or an emergency tire puncture repair kit is used• When the rear washer is operating
• If the suspension has been modified or tires of a size other than specified are installed.
• If an electronic component, such as a backlit license plate or rear fog light, is installed near the rear camera
• If a bumper protector, such as an additional trim strip, is installed to the rear bumper
■Situations in which the system may
operate unexpectedly
●Even though there are no pedestrians
in the detection area, some objects,
such as the following, may be detected, possibly causing the rear camera detection function to operate.
• Three dimensional objects, such as a pole, traffic cone, fence, or parked vehicle
• Moving objects, such as a car or motorcycle• Objects moving toward your vehicle
when backing up, such as flags or puddles (or airborne matter, such as smoke, steam, rain, or snow)
• Cobblestone or gravel roads, tram rails, road repairs, white lines, pedes-trian crossings or fallen leaves on the
road • Metal covers (gratings), such as those used for drainage ditches
• Objects reflected in a puddle or on a wet road surface• Shadows on the road
●In some situations, such as the follow-ing, the rear camera detection func-
tion may operate even though there are no pedestrians in the detection area.
• When backing up toward the roadside or a bump on the road• When backing up toward an
incline/decline • If the rear of the vehicle is raised or lowered due to the carried load
• If a bumper protector, such as an additional trim strip, is installed to the rear bumper
• If the orientation of the rear camera has been changed• If a towing eyelet is installed to the
rear of the vehicle • When water is flowing over the rear camera lens
• When the rear camera is obscured (dirt, snow, ice, etc., are attached) or scratched
• If there is a flashing light in the detec- tion area, such as the emergency flashers of another vehicle
• When a tire chains or an emergency tire puncture repair kit is used
